People are using Groups to communicate with many of the important communities in their lives, like their families, best friends, and teammates. My own family uses a group to stay connected to each other. As a Californian with a brother living in Peru and parents back in Wisconsin, we use our group to update each other about our lives, share vacation photos, and discuss where we're going to meet up next.
A year ago, we launched the Like button, which gives you a quick way to share the things you find on the web with all your friends. But there are times when you find something that you only want to share with a few specific people.
